    "content": "## Immediate resuscitation phase\n\n**Vascular access:** A large-bore intravenous catheter is established. If IV access cannot be obtained, intraosseous access is used.\n\n**Initial fluid bolus:** 20 mL/kg of isotonic fluid (normal saline or lactated Ringer solution) is administered over approximately 20 minutes.\n\n**Fluid choice:**\n- **Normal saline or lactated Ringer solution** is used for initial resuscitation\n- In children with isolated vomiting and probable metabolic alkalosis, **normal saline** is used (lactated Ringer solution or Plasma-Lyte is avoided)\n- Lactated Ringer solution or Plasma-Lyte may be preferable to normal saline in shock as balanced solutions\n\n**Reassessment and repeat boluses:** Vital signs are monitored closely. Repeat boluses of 20 mL/kg may be needed. The child may require multiple boluses administered as rapidly as possible. Up to 20–100 mL/kg total may be required to restore plasma volume and pulses.\n\n**Monitoring:** Return of normal pulse and state of consciousness is assessed. Hypotension and orthostatic vital sign changes are monitored. Peripheral perfusion and mental status are evaluated.\n\n**Urine output:** Urine output is monitored; normal output is approximately 1 mL/kg/h. If the patient does not void after 3 fluid boluses, a bladder catheter is inserted.\n\n**Escalation:** Any child requiring more than 40 mL/kg as a bolus should be urgently reviewed for need of vasopressor or inotropic support and consideration of intensive care.\n\n## Laboratory assessment\n\n**Electrolytes:** Serum electrolyte levels, BUN, and creatinine are determined.\n\n**Potassium:** Intravenous potassium is withheld until urine output is established.\n\n## Deficit replacement phase\n\nOnce shock is reversed and mental status is satisfactory, the remaining fluid deficit is replaced over 12–24 hours using isotonic fluid. Dextrose and potassium are added to ongoing fluids as appropriate.\n\n## Transition to oral rehydration\n\nWhen the child's condition has stabilized and mental status is satisfactory, oral rehydration therapy is initiated. The intravenous line is maintained until oral intake is adequate.\n\n**Alternative:** Enteral hydration via nasogastric tube is considered for patients who refuse oral intake but do not have ongoing vomiting.\n\n## Poor response to resuscitation\n\nLack of response to initial resuscitation or persistently poor perfusion despite multiple boluses suggests an underlying problem such as [[178|septic shock]], toxic shock syndrome, [[100|myocarditis]], myocardiopathy, or pericarditis. Broad-spectrum antibiotics and vasopressors are given, and the patient is transferred to an intensive care unit."

A detailed history of pain location and severity, fever, respiratory symptoms, and any recent infections or triggers is obtained. A thorough physical examination is performed, including vital signs, assessment for acute chest syndrome (chest pain, dyspnea, cough with pulmonary consolidation), splenic enlargement, and signs of sepsis.\n\n### Diagnostic Approach\n\nFor newly identified cases or confirmatory diagnosis:\n- Hemoglobin electrophoresis\n- High-performance liquid chromatography (HPLC)\n- Immunologic tests\n- Molecular genetic testing\n\nNote: If the child has received a blood transfusion, testing is delayed until more than 90 days after transfusion.\n\n### Comprehensive Care Framework\n\nAll children with sickle cell disease require coordinated comprehensive care through a medical home with appropriate expertise. This includes:\n\n- **Ongoing education** for patient and family regarding disease management, pain recognition, and when to seek emergency care\n- **Periodic comprehensive evaluations** to monitor for complications\n- **Disease-specific health maintenance services** tailored to prevent and detect complications early\n- **Psychosocial support** to address the emotional and social impact of chronic illness\n- **Genetic counseling** for family members\n\n### Acute Illness Management\n\nTimely and appropriate treatment of acute complications is critical. Acute presentations may include:\n- Vaso-occlusive pain crises (musculoskeletal and abdominal)\n- Acute chest syndrome\n- Splenic sequestration\n- Bacterial [[226|sepsis]] or [[147|meningitis]]\n- Stroke\n- Priapism\n\nRapid assessment and intervention are essential as complications can become life-threatening within hours."

Combined screening protocols incorporating maternal age, nuchal translucency, and maternal serum markers enable early detection.\n\n**Postnatal Assessment**\n\nAt birth, examination is performed for characteristic dysmorphic features: overlapping fingers in clenched fist, short sternum, rocker-bottom feet, prominent occiput, and low-set ears. Reduced birth weight and small placenta are documented. Signs of fetal distress are assessed.\n\n**Cardiac Evaluation**\n\nCongenital heart disease is present in the majority of cases. Echocardiography is obtained to identify structural lesions (VSD, PDA, ASD, polyvalvular disease). Signs of heart failure and pulmonary hypertension are monitored.\n\n**Feeding and Nutrition**\n\nPoor feeding is common. Nasogastric tube feeding is often necessary. Growth charts specific to trisomy 18 should be used for monitoring.\n\n**Respiratory Support**\n\nCentral apnea and hypoventilation are major causes of mortality. Respiratory monitoring and support are provided as clinically indicated.\n\n**Diagnostic Confirmation**\n\nG-banded karyotype analysis is the study of choice to confirm diagnosis and determine recurrence risk. This is particularly important if translocation is suspected, as recurrence risk is higher for translocation carriers and depends on the chromosomes involved and the sex of the carrier parent."

Congenital [[171|hypothyroidism]] should be considered in any infant presenting with significant constipation, prolonged jaundice, hypotonia, or hypothermia.\n\nDiagnosis is confirmed with TSH measurement ideally after 48 hours of age (minimum 24 hours). TSH elevation above a threshold of 20 μL indicates congenital hypothyroidism. In suspected central hypothyroidism, clinical suspicion is required as TSH-based screening may miss these cases.\n\n**Treatment Initiation**\n\nLevothyroxine replacement therapy is begun as quickly as possible after diagnosis, with the goal of initiating treatment by 2 weeks of age. The passages do not provide specific dosing information for levothyroxine.\n\n**Monitoring and Follow-up**\n\nResolution of clinical manifestations is monitored. Neonatal cholestasis, if present, typically resolves with appropriate hormone supplementation. Associated [[115|congenital anomalies]], particularly cardiac anomalies, are assessed, and hearing is evaluated. In infants with central hypothyroidism or pan-hypopituitarism, adrenal insufficiency is screened for, as delayed treatment may lead to severe consequences including death."

Maintenance and replacement fluids are also provided. Deficit plus maintenance calculations often approximate 5% dextrose with 0.45% or higher saline.\n\n**Step 4: Manage by Volume Status**\n\n**Hypovolemic hyponatremia:** Intravascular volume is first restored with normal saline boluses of 20 mL/kg as needed to correct the volume deficit. Hypotonic fluids are then provided to further replace the water deficit. Note that even normal saline (osmolality 308 mEq/L) is hypotonic relative to hypertonic serum and allows gradual sodium reduction.\n\n**Hypervolemic hyponatremia:** Both sodium and water intake are restricted, and the underlying disorder is corrected. If due to water intoxication (characterized by maximally dilute urine with specific gravity <1.003), water is restricted.\n\n**Step 5: Monitor and Avoid Complications**\n\nOverly rapid correction is avoided, as it can cause osmotic demyelination syndrome, cerebral dehydration, and seizures. Serum sodium is monitored regularly to ensure correction remains within safe limits."

Videography can document excessive nocturnal movements in suspected restless sleep disorder.\n\n**Management Approach**\n\nManagement begins with behavioral interventions addressing sleep hygiene: consistent bedtimes and wake times are established, a structured bedtime routine is implemented, electronics are removed from the bedroom, and caffeine intake is eliminated.\n\nFor children with autism spectrum disorder or depression presenting with [[377|insomnia]], cognitive behavioral therapy is an evidence-based treatment option. Melatonin or medications may be considered in autism-associated insomnia when behavioral interventions are insufficient.\n\nIn restless sleep disorder associated with low serum iron levels, iron supplementation should be considered, with symptomatic improvement expected following treatment.\n\nFor medication-related sleep disturbance in ADHD, timing and type of stimulant or nonstimulant medication are reviewed, with consideration for dose adjustment or alternative agents in consultation with the prescribing clinician.\n\nUnderlying psychiatric conditions (depression, anxiety, bipolar disorder) are addressed with appropriate pharmacotherapy and psychotherapy as indicated, which may improve associated sleep disturbance."

Chest radiograph is obtained to assess for cardiomegaly, pulmonary vascularity, and venous congestion\n\n**Medical Management (Acute Phase)**\n\n6. Heart failure is treated:\n   - Fluid intake is restricted\n   - Diuretics are administered as needed\n   - Nutrition is optimized and growth is monitored\n7. Complications, including pulmonary [[92|hypertension]], are monitored for\n\n**Definitive Treatment**\n\n8. Referral for surgical repair is made at 3–6 months of age\n   - Procedure involves separating the common valve into mitral and tricuspid components\n   - Closure of atrial and ventricular septal defects"
